One of the deepest principles of interaction design I observe is that, except in special cases, the articulation of a user interface should suggest something of a device, service or application’s capabilities and affordances. This is clearly, thoroughly and intentionally undermined in Apple’s current suite of iOS offerings.

Very interesting, I like the Calendar app, but most of the others he mentions I don’t care for. It is clear that Apple uses this design metric to make things familiar, what is unclear is whether they actually like designing this way. [via Daring Fireball]
